Summary

This study shows electromagnetic navigation systems (ENS) can improve aortic arch branch cannulation and fenestrated endograft deployment. Using ENS with 2D imaging reduced radiation exposure and improved performance compared to 2D alone.

Area of Science:

  • Vascular Surgery
  • Medical Imaging
  • Interventional Radiology

Background:

  • Electromagnetic navigation systems (ENS) offer advanced visualization for complex endovascular procedures.
  • Aortic arch branch cannulation and fenestrated endograft deployment require precise navigation.
  • Evaluating novel navigation technologies is crucial for improving patient outcomes.

Purpose of the Study:

  • To assess the in vitro efficacy of an electromagnetic navigation system (ENS) for aortic arch branch cannulation.
  • To determine the role of ENS in fenestrated endograft deployment within the visceral segment.
  • To compare ENS performance against traditional 2D imaging modalities.

Main Methods:

  • Silicone phantoms of the aortic arch and thoracoabdominal aneurysm were used for in vitro testing.

  • Nine operators performed cannulation using ENS, 2D imaging, or a combination.
  • Procedure times, wall hits, and qualitative scores (IC3ST) were analyzed. ENS was also used exclusively for fenestrated stent-graft deployment.

    • Main Results:

    • Combined ENS and 2D imaging reduced fluoroscopy times and wall hits compared to 2D alone.
    • The combined approach also improved IC3ST performance scores.
    • ENS enabled successful cannulation of all 4 visceral vessels during fenestrated endograft deployment.

    Conclusions:

    • Electromagnetic navigation systems (ENS) can serve as a valuable complementary imaging tool.
    • ENS may reduce radiation exposure and enhance cannulation performance.
    • The system aids in precise positioning of intravascular devices like fenestrated endografts.
